Statement-1: You see a geostationary satellite above the horizon. You desire to communicate with the satellite by sending a beam of laser light. You should aim your laser slightly higher than the line of sight of the satellite.
Statement-2: Light bends away from the normal while moving from denser to rarer medium.

State whether the following statements are True or False : When a light ray travels obliquely from an optically rarer medium to an optically denser medium, it bends away from the normal.

STATEMENT- 1 A fish inside a pond will see a person standing outside taller than he is actually. STATEMENT 2 Light bend away from the normal as it enters water from air.

Read the statements given below and identify the concepts explained in them. When Reema observes a light ray coming from medium 2 into medium 1, she sees that the ray bends away from the normal while entering the medium 1. Which medium in this case is optically rarer?

I will never forget that day. It was a day in BSF academy at Tekanpur. We were a batch of 96 officers being taken for an intensive training in arms. Of these, 20 of us engineers and IITians. Having studied projectile motion during our school days, we were quite keen to see it being demonstrated in case of. weapons, the man showing us the demo was using an AK-47 fitted with tracer bullets. As they were fired, we could actually see them, they would emit light. First of all the man fired at the center of the target 30 m away while firing horizontally. We could actually see the bullet moving in a parabolic path and hitting 2 cm below the target. ''You see. That is what I said. For accurate firing you need to aim not at the target but slightly above.'' (g = 10 m//s^(2)) What was the initila velocity of the bullet?

Noor, a young student, was trying to demonstrate some properties of light in her Science project work. She kept ‘X’ inside the box (as shown in the figure) and with the help of a laser pointer made light rays pass through the holes on one side of the box. She had a small butter-paper screen to see the spots of light being cast as they emerged. Her friend noted the following observations from this demonstration: i. Glass is optically rarer than air. ii. Air and glass allow light to pass through them with the same velocity. iii. Air is optically rarer than glass. iv. Speed of light through a denser medium is faster than that of a rarer medium. v. The ratio: sin of angle of incidence in the first medium to the ratio of sin of angle of refraction in the second medium, gives the refractive index of the second material with respect to the first one. Which one of the combination of the above statements given below is correct.
